博客、维基和社交网站等Web 2.0应用存在具有挑战性的隐私问题。许多用户没有意识到搜索引擎会对这些网站上的个人信息进行索引，并提供对所收集数据的公开访问。结果，隐私侵犯现象十分猖獗。在本文中，我们证明基于标签的隐私策略是一种适用于Web 2.0应用的可用且灵活的隐私控制方法。内容所有者根据内容对象上的标签来表达其隐私策略；然后系统根据分配给对象的标签将策略应用于对象。我们将基于标签的隐私控制作为WordPress博客系统的一个插件来实现，并进行了一项用户研究，以衡量用户是否能够使用基于标签的策略有效地解决现实世界中的隐私问题。尽管时间和培训有限，但三分之一的参与者选择了基于标签的策略工具。与基于每个对象的隐私控制相比，这些用户使用我们基于标签的隐私控制能够以相同的准确性和更快的速度执行与隐私相关的任务。
Web 2.0 applications such as blogs, wikis and social networking sites have challenging privacy issues. Many users are unaware that search engines index personal information from these sites and offer public access to collected data. As a consequence, privacy invasions are rampant. In this paper, we demonstrate that tag-based privacy policies are a usable and flexible privacy control method for Web 2.0 applications. Content owners express their privacy policy in terms of tags on content objects; the system then applies the policy to objects based on the tags assigned to them. We implemented tag-based privacy controls as a plugin to the WordPress blogging system, and conducted a user study to measure whether users could efficiently address real-world privacy concerns using tag-based policies. Despite limited time and training, a third of the participants chose the tag-based policy tools. These users were able to perform privacy-related tasks with the same accuracy and increased speed using our tag-based privacy controls versus per-object privacy controls.
